We posted a set of Gossip Girl 100th episode photos yesterday, offering our first glimpse inside the royal wedding of Blair Waldorf. Now the CW has released its synopsis for the show's century-mark installment,"G.G."

According to the network, the January 30 episode "will open with a musical dream sequence featuring Serena, Blair and all the men in their lives (Louis, Chick, Dan and Nate)."

Also, "while Chuck wrestles with the reality that Blair is about to walk down the aisle with Prince Louis, the return of Georgina Sparks might make the royal affair a royal disaster."

We know from the photo gallery that Blair makes it to the altar, but whether any vows are actually exchanged remains the million-dollar question. Think Chuck, Georgina or both will put a stop to this wedding?

Two more episodes remain before the 100th, with Gossip Girl returning Monday with the car accident's aftermath, then indulging in bachelorette party fun a week later. It all builds up to the big day. What will happen?
